The following are some general recommendations or guidelines to follow when applying a pressure-sensitive adhesive tape:
- Make sure the surface you are applying the tape to is completely dry and free of any debris before the tape is applied.
- If any cleaning supplies were used recently on the surface please make sure no residue remains from the cleaning product (if so please use water to remove and then let it dry completely).
- Unwind the tape from the roll (if the tape has a release liner remove it now). During this step be careful not to contaminate the adhesive by touching it at all with your fingers since it will transfer natural oils over to the adhesive side. Also try to immediately bond the tape to the surface without entrapping air between the tape and the surface it is being applied to.
- Use some application pressure (it doesn't have to be that forceful) in order to achieve maximum bond strength. Make sure there is no gapping remaining between the tape and the surface it is being applied to which would allow water to come into contact with the adhesive-side of the tape over time. This would deaden the adhesive and shorten the life span of the tape.
- If the tape has an acrylic adhesive the dwell time the tape needs to be in contact with both surfaces (before it reaches it maximum adhesion) is typically 1 to 24 hours. For best results during this dwell time try to provide some application pressure (e.g. clamps, tape over it, etc.); also if holding an item vertically against a surface try and support the weight if possible.
- For even better adhesion you can also use an adhesion promoter or primer; can see some options at Adhesion Promoter/Primer on FindTape.com.
Scapa has recently discontinued their 142 economy-grade duct tape which our converter had log roll stock in so they were able to offer it in wider widths. They've recently starting stocking log rolls of Polyken GP2280 (available in black, blue, green, olive drab, red, silver, white and yellow) and Nashua 395 (offered in brown and tan) as an alternative. Both tapes are 9 mils thick and are for general or multi-purpose use and they have similar specifications.
During Permacel’s move out of Wisconsin to New Jersey they located an unsold jumbo roll of P-99 that was made at the end of 2008 which they re-certified (the certificate of conformance is here and the shelf life is dated through 7/14/2010). The tape is on Nitto cores (Nitto Denko is phasing out the Permacel name now). The entire jumbo was cut to a 1" width and that inventory has now been added to the web site here.
Shurtape has recently introduced a new glow-in-the-dark gaffers tape called P-661. It has the same adhesiveness and clean removability characteristic of Shurtape P-665 gaffers, but gives you the added benefit of being photoluminescent after the tape is activated by an artificial or natural light source. It is also hand tearable just like a traditional gaffers tape. It has numerous uses including, but not limited to basic stage safety marking (e.g. exists and stairs).

Nashua has recently released two new tarp tapes designed for extended outdoor exposure. Nashua 680004 Heavy Duty Tarp Tape is single-sided black polyethylene film tape which can be used to seal and seam heavy-weight poly tarps. It is designed for 6 to 8 months of outdoor exposure. Nashua 680006 Double-Sided Tarp Tape is a cloth tape with adhesive on both sides which comes on a blue film release liner. It is also used to seam heavy-weight tarps and is suitable for up to 12 months of outdoor exposure. The tapes are available in a 2 inch width and limited inventories of both are now in stock.
Our converter has recently received in tons of overstock high-temperature masking tape from one of the major manufacturers. They've already cut a bunch of it to 2-inch width and it is now available for sale by the case (18 rolls come in a case) for just $23.22 - see JVCC MT-SALE for information and pricing on the tape. A case of 2-inch high-temperature masking tape typically sells for over $100 per case. They also have log rolls available and pricing for widths from 1/4" up to 8" can be seen by looking at the JVCC MT-02 product. The MT-02 product doesn't have any case requirements and all the listed widths can be purchased in single-roll quantities. Thank you.
After running out of our stock of Nashua Big Fix Duct Tape Patch rolls last year we've recently received in more of this overstock item from Nashua. This time both 15-foot and 30-foot long rolls are available for purchase. Both 12-inch wide silver lengths come in a retail packed box with a convenient side cutter. The duct tape comes on a fast removing paper release liner. It is typically used for repairing holes in items like plastic sheeting and tarps. Also used for quick fixes for car body damage and around doors and windows.
It’s always been easy to order multiple colors of a tape when ordering full cases, but very time consuming when ordering individual rolls. Now we’ve made it much faster. If you want to order single rolls of a tape in multiple colors or sizes, here’s what you do:
Let’s say you’re a hooper and you want to purchase single rolls of the 3/4" JVCC V-36P vinyl tape in all 17 colors it is offered in. Just add one of the items, in any desired color, to your cart. You’ll then see a pop-up window where you should click on "Continue Shopping". At that point all you need to do is change the color selection (the quantity will have already been saved) and click "Add to Cart" again. Do this until all of your desired colors have been placed in your cart.
The “Continue Shopping “ button avoids numerous clicks where you’d have to first get back to the JVCC V-36P product page before placing the new color in your shopping cart. I hope this simplifies the ordering process for those of you who are ordering single rolls of different colors or sizes of the same product.
Since P-99 is now discontinued and no longer being made by Permacel (we currently only have some 1/2" wide stock remaining) we keep on getting asked for a suitable replacement tape. Primarily since Permacel P-99 was written into the ASTM D3359-09 measuring adhesion by tape test standard. 3M 720 is a tape of similar construction (polyester film/paper fiber carrier with a rubber adhesive); however 720 is not specifically written into the test standard and it is also now discontinued. We contacted ASTM about the situation and they said they have not recommended a substitute tape yet, but they said they would be discussing replacement tapes at their next meeting in January. If any recommendations come out of that meeting we will follow-up here.
UPDATE (2/14/2010): The last update we received from the ASTM D01.23 subcommittee was that D3359 has not been revised yet and that the committee needs to complete a round robin. Comparative tests are being planned on 3 tapes: Intertape LA-26, Scapa 8010B and CHT-1. A round robin will result from the tests and then D3359 will be updated afterwards.
