Bondtite SR Adhesives
Bondtite Standard SR is a dark brown colour synthetic rubber based contact adhesive. It is a general purpose adhesive suitable for bonding variety of substrates such as Rubber, leather, Mica, EVA, rexin, foam and canvas. It is general purpose adhesive for flexible substrates. Also used for vertical laminates application.
- Wood to Mica
- Carpet lying
- Leather articles
- Mattress and upholstery
- Excellent bond strength
- Ease of application with good coverage
- Good tack and tack retention time
- Mild smell
- No harmful benzene
Surface preparation: Ensure that substrates to be bonded are clean, dry and free from oil, grease and foreign particles such as dust and rust.
Application method: Stir adhesive well and make it homogeneous prior to use. Apply adhesive uniformly in thin layer on both the substrates to be bonded with brush, spatula or any suitable tool. Allow evaporation of solvents from adhesive layer to develop tack. The evaporation of solvent may take 5 minutes to 10 minutes, which depends upon ambient Temperature and humidity. In case of absorbing substrate, apply second coat and allow drying for 5 minutes to 10 minutes. Assemble both the substrates with uniform contact pressure to achieve intimate contact without air pockets. The optimum bond strength is achieved after 24 hours.

*(Tack retention time (open time) is generally measured after evaporation of solvent once adhesive applied in thin film. It may vary depending upon ambient temperature and humid conditions.)
18 months in a partially filled packing and strictly store in cool, away from heat.

Bondtite Standard SR should be stored in cool and dry place away from moisture, heat and direct sunlight. It contains highly volatile solvents, which will release during application, processing and use. These volatile solvents are highly flammable, hence adhesive must not come in contact with heat, spark and necked flame. Please refer to the Safety Data Sheet (SDS) for detailed instructions on storage and handling.
