3M 7100062120 | AC63 1.52 fl oz Capacity Transparent Accelerator

3M Polyurethane Adhesive Sealant Accelerator AC63 is a liquid additive that, when combined as a part of a two-component adhesive system, accelerates the curing of the adhesive. It is capable of drastically reducing the handling time of adhesives used in highly productive construction settings.

3M empowers its customers by designing the solutions that bring optimal performance to their everyday applications. 3M Polyurethane Adhesive Sealant Accelerator AC63 is designed for large applications where adhesive strength and cure time are factors. When this adhesive accelerator is combined with an adhesive in a two-part adhesive system, it is capable of reaching full strength in a fraction of the time it takes conventional, single-part polyurethane adhesives. Consistent, guaranteed cure rates can be achieved in less than an hour, while a tack-free state can be achieved within 15 (+/-5) minutes.

With a curing process unlike that of the single-part polyurethane adhesives on the market, this two-part accelerated polyurethane mixture of 3M Polyurethane Adhesive Sealant Accelerator AC63 and 3M Polyurethane Adhesive Sealant 550 is capable of curing due to a chemical process as well as a moisture-based process. This process actually cures the adhesive from the inside out, resulting in a more consistent cure that reaches full strength in a fraction of the time. No exothermic reaction takes place, no priming is required (for most applications)and the adhesive mixture does not stain.

Features:

• Provides a faster cure when mixed in a two-component sealant system
• Adhesive mix is tack-free within 15 (+/-5) minutes
• Consistent curing can be achieved within 60 minutes
• To be used with 3M Polyurethane Adhesive Sealant 550 in 350mL Sausage Packs
• Provides excellent weather resistance
• Non-staining formula prevents discoloration
