Abstract
The adhesive comprises (1) a mineral component, consisting of (a) 20-90 (wt)% conc. aq. soln. of an alkali metal silicate, (b) 5-25% clay and (c) 2-7% deflocculated asbestos fibre, and (2) an organic component in the form of a 30-70% aq. soln. of carboxymethylcellulose (CMC), a starch ester and/or a dextrin, the amt. of this component as dry matter, being 0.2-2 wt. % of the adhesive. Used for bonding Al, black plate (untinned iron plate), glavanised or Zn electroplated plate, glass, cement etc. to wood plywood, fibreboard, expanded polystyrene boards phenolic resin, polyurethanes etc. wood to wood or expanded polystyrene boards, plush materials to floors etc. and for giving materials of this type a nonflammable and flame-resistant coating. The adhesive has long pot life, gives strong bonds, is very resistant to temp. and is free from toxic gases. The dried adhesive film acts as fire retardant.
