Underground / Concrete

This family of hot melt materials is designed for use as very aggressive tack lower cohesive strength pressure-sensitive adhesives. It has a very high “quick-stick” and tack properties, but only fair shear strength. It has very good environmental stability and moderate peel strength. It is ideal for use in many environments where a system is needed for difficult to adhere substrates especially in construction applications. It can be used as a backing for tapes, foams including Styrofoam and various materials where a pressure sensitive nature is needed. The viscosity is designed to allow it to be applied via foam melt, spray, or swirl-spray.

This product was designed to control the ingress and egress of water at control joints in concrete and dissimilar products. The design of this product is such that it will swell between 200% and 300%.

This product is a quality sealing tape developed for use in metal duct connection systems and metal building construction. It has been used successfully for over twenty years. During this time, the tape has been tested for sensitivity to numerous chemicals normally found in duct work and a library of chemical resistance data has been developed. Q-205 has the widest range of application temperatures (see Hardness and Force to Compress) of any competitive material ensuring a positive seal and ease of application under extreme conditions. It is a non-hardening and has an extremely good adhesion to galvanized, Galvalume©, aluminized metal, stainless steel and other metal surfaces.

Mastagum is a soft, permanently pliable, water-resistant sealant having a wide variety of applications. It has the unique quality of retaining the same consistency throughout its application range of 20°F to 140°F (-7° to 60°C).
