Chemlok 402X-HS Adhesive
Solvent-based adhesive for bonding textiles to elastomers
Chemlok 402X-HS adhesive is a solvent-based, one-coat adhesive designed for bonding textiles to a wide variety of unvulcanized elastomers. Chemlok 402X-HS adhesive is an all-xylene version of Chemlok 402 adhesive. It is composed of a mixture of polymers, organic compounds and fillers dissolved or dispersed in an organic solvent system. Chemlok 402X-HS adhesive is used in the production of hoses, belts, diaphragms and other textile-reinforced rubber products. It can also be used as an additive to tie cements, primarily as a replacement for isocyanates that are widely used in rubber/textile bonding. When dried, Chemlok 402X-HS adhesive is tack-free.

Features and Benefits
- Versatile - bonds a variety of elastomers to a wide variety of textiles during vulcanization of the elastomer.
- Non-chlorinated Solvent System - suitable for solvent incineration, saving cost of recovery equipment.
- Excellent Adhesion - adheres well to RFL-treated fabric or cord. Chemlok 402X-HS adhesive-treated fabric or cord can be bonded immediately following solvent evaporation.
- Convenient - requires only a single coat for most applications, reducing labor, solvent usage, inventory and shipping costs.

Shelf Life & Storage
Shelf life is six months from date of shipment when stored by the recipient in a well ventilated area at 21-27 C (70-80 F) in original, unopened container. Do not store container outside. Chemlok 402X-HS adhesive is moisture sensitive. Minimize exposure to moisture by preparing only what is needed for several hours of use.
