Cyanoacrylate Instant Adhesive WEICON Contact VA 2500 HT LOCTITE 421
Due to its curing with residual elasticity, WEICON Contact VA 2500 HT is particularly suitable under changing climatic conditions. It is insensitive even to prolonged exposure to humidity. Contact VA 2500 HT is suitable for the bonding of the most diverse rubber materials and plastics and also for metal/plastic joints. VA 2500 HT can be used in many different industrial areas.
LOCTITE® 421 is a clear, colorless to straw yellow, 1-part, medium viscosity, liquid cyanoacrylate adhesive for bonding difficult-to-bond materials which require uniform stress distribution and high tensile shear strength. The product provides rapid bonding of a wide range of materials, including metals, plastics and elastomers. It is particularly suited for bonding porous or absorbent materials.
