'3M RP45' is out of stock and not currently available for purchase on the site.
3M RP45 VHB Tape is a double-sided permanent assembly tape which bonds high and medium surface energy substrates. Provides handling convenience, cushioning, damping, and impact resistance. RP45 comes on a paper release liner. This newer RP family of 3M VHB tapes has an all acrylic construction which gives the tape extraordinary strength, conformability, and versatility. The composition of 3M VHB RP resists UV and weather damage, making it a great solution for outdoor applications. It bonds to a wide variety of surfaces, including glass, metal, many plastics, composites, sealed wood, and painted surfaces. Rough, porous or fibered materials such as wood, particleboard, cement, etc., have an open surface and require sealing to provide a unified bonding surface for 3M RP45 VHB tape. Common sealing materials would include paint, varnish or other hard surface coatings.
3M VHB Tape provides the convenience and simplicity of a tape fastener and are ideal for use in various interior and exterior structural bonding applications. In many situations, they can replace rivets, spot welds, liquid adhesives, and other permanent fasteners. These VHB tapes are made with an acrylic foam which is viscoelastic in nature. This gives the foam energy absorbing and stress relaxing properties which provides these tapes with their unique characteristics (see http://solutions.3m.com/wps/portal/3M/en_US/Adhesives/Tapes/Brands/3M-VHB-Tape/ for videos showcasing its properties). Acrylic chemistry provides outstanding durability performance. The tapes have excellent durability and excellent solvent and moisture resistance. Country of Origin: United States.

QUESTION: HelloI need to put a back spoiler in my car and need the more strong 3m double side for it wich one is the best you can recommended for it from your shopThank you
: For permanent structural mounting on vehicles we would recommend one of 3M's auto attachment VHB products - please see: http://www.findtape.com/shop/results.aspx?keywords=auto+attach+double
for the four we sell. The main difference between them is in the thickness of the tape. 3M auto attachment tape, like all double-sided VHB style tapes, is coated with an acrylic adhesive so it has a 1 to 24-hour dwell time before its maximum adhesiveness or bond strength is reached. It won’t feel as tacky to the touch though like a tape coated with a rubber adhesive, e.g. duct tape, etc. It is recommended to try to provide pressure during this time (e.g. clamps, tape over it, etc.) if you can so that the adhesive bond can form correctly. For even better adhesion on substrates including glass and glass-like materials; copper and copper containing metals; and plastics or rubber that contain components that migrate (e.g. plasticizers) you will want prepare the surface with an adhesion promoter or primer - can see some options at: http://www.findtape.com/category176/adhesion-promoter-primer.aspx
For full details on surface preparation can see write-up from 3M:https://static.findtape.com/specifications/3M-VHB-Surface-Prep.pdfThank
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.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
Lower gauge gloves are heavier - have thicker construction, fewer stiches knitted per inch and offer less dexterity.
Higher gauge gloves are lighter - have thinner/finer construction, more stitches knitted per inch and offer more dexterity.
Gloves offered typically runs from 7 to 18 (12 and 13 are in the middle of the scale).
