- Shake 3M Primer 94 well before using (for the ampules need to squeeze in the middle until hearing a pop to break the inside vessel).
- Apply a thin uniform coating to the bonding surface using the minimum amount that will fully coat the surface.
- Allow 3M Primer 94 to dry thoroughly before applying tape. This is usually accomplished in 5 minutes at room temperature. Be sure the primed surface remains free from contaminants prior to applying the tape.
- Porous surfaces may require 2 applications of 3M Primer 94 for uniform coverage and good adhesion.
Allow the first application of primer to dry before applying the second coat.

Grigoria Kamaterou Jan 23, 2023
QUESTION: Good morning
I'm looking for the best double sided tape for leather and wood that don't damage the wooden surface when removed
Kindly let me know if I need to use primer and which tape
ANSWER: As long as the wood is sealed first (most adhesive products won't adhere long on unsealed woods) then can try a gaffers tape such as Pro Tapes Pro-Gaff. Please note though that gaffers tape usually removes cleanly for up to several months if not exposed to UV light. If exposed to UV light then may want to check on using a painters tape, but typically the maximum time painters tape removes cleanly is 14 to 30 days. Thank you.

Excellent product easy to use.
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
