GENERALITY

Ready-to-use vinyl acetate adhesive in aqueous dispersion for the wood industry. It is characterized by medium viscosity, open time and medium-long setting time. Recommended for general bonding.

TYPICAL APPLICATIONS

It is used in the wood industry such as:

- General glue for joinery

- For the construction of softwood frames

- For cladding of plywood and non-fireproof chipboard panels

- For bonding paper, cardboard, expanded polystyrene

USEFUL ADVICE FOR USE

- It is applied by means of automatic or manual spreaders, by brush, etc., in a uniform and not excessively abundant layer on one of the surfaces to be glued. In particular cases, in order to increase the adhesive power, it is possible to use the coating on both surfaces. The dosage of adhesive must be adequate, excessive quantities delay setting, small quantities produce defective gluing.

- The materials to be bonded must be free from dust or anti-adhesive substances such as greases, oils, paraffins, etc.

- The surfaces of the adherents must be provided exactly matching. Too high coupling tolerances generate precarious bonding.

- Make sure that the temperature of the work environment and materials is at least 18 ° C. With the lowering of the real working temperature, the times for adhesion are extended and the bonding is no longer reliable. Before gluing, the wood must be conditioned for a few days at 18-20 ° C.

- The humidity must be controlled. A high humidity of the wood does not favor the complete drying of the adhesive, on the other hand a reduced humidity forcibly accelerates its filming.

- The pressure on the two surfaces to be joined, of a minimum value that allows the intimate effective contact between the parts, must be applied within the limits of the open time until a sufficient initial adhesive force is obtained.

- The glue must not remain in contact with unprotected iron tools or containers. Recommended are containers in stainless steel, enamelled steel, reinforced polyester, plastic materials such as PVC, PE.

- The glue must be used as it is, without additions or modifications of any kind. A small addition of water can be tolerated if the product is too viscous in use.

- After a long period of storage it is advisable to remix the adhesive before using it.

- On new materials or materials which have been stored for a long time, always check their bondability by means of suitable preliminary bonding tests.

- To clean tools and containers, use water, preferably lukewarm.

STORAGE

Store in original closed packaging, in a temperate environment (+5 / + 30 ° C.).
