TREMstop Acrylic is a gunnable acrylic latex sealant designed for use in firestop applications, including both joints and through-penetrations.
TREMstop Acrylic is for use on metal pipe, plastic pipe, insulated pipe, cables, cable trays, ducts, static joints and dynamic joints in fire-rated concrete, wood floor/ceiling and gypsum wall assemblies. TREMstop Acrylic can also be used on sound rated assemblies.
Features and Benefits
TREMstop Acrylic is an easy to apply, all-purpose sealant that accepts paint once fully cured. It features excellent movement and superb unprimed adhesion to a wide range of substrates. When installed in accordance with a tested firestop system,
it affords code compliance for both through-penetrations and fire-rated joints.
At 77°F (25°C), 50% RH, TREMstop Acrylic is tack free in 30
– 60 minutes and dries at a rate of about 1/8” per day. As the temperatures decrease, the dry time of TREMstop Acrylic will increase, generally one additional day for every 10°F decrease in temperature.
For good adhesion, the substrate must be sound, clean and dry. Any surface damage, dirt, dust, loose particles or other contaminants that may inhibit adhesion must be removed from the surfaces prior to application of the sealant.
Tremco recommends that surface temperatures be 40 ̊F (5 ̊C) or above at the time the sealant is applied. If sealant must be applied in temperatures below 40 ̊F, please refer to the Tremco Guide for Applying Sealants in Cold Weather that can be found on our web site at www.tremcosealants.com.
Priming is not required.
