Fevicol SR 998 – Synthetic Rubber Adhesive (Industrial Grade)

Fevicol SR 998: Industrial Grade Synthetic Rubber Contact Adhesive

Fevicol SR 998 is a premium, solvent-based synthetic rubber contact adhesive designed for heavy-duty industrial and professional applications. Renowned for its superior bonding strength and fast tack development, this adhesive is the trusted choice for permanently joining challenging non-porous materials like rubber, PVC, leather, foam, and laminates. Its high-grade formulation ensures durability and resistance to water and heat.

Unlike general-purpose glues, Fevicol SR 998 forms an instant, powerful bond upon contact, eliminating the need for extensive clamping. This makes it indispensable for high-speed assembly and manufacturing processes where strength and speed are paramount.

Why Choose Fevicol SR 998?

SR 998 offers exceptional performance for complex bonding needs:

• Industrial Strength: Provides a robust, durable bond suitable for heavy-duty usage and manufacturing environments.
• Fast Contact Bond: Develops high green strength immediately upon surfaces being pressed together, significantly reducing or eliminating clamping requirements.
• Versatile Substrates: Excellently bonds diverse non-porous materials where PVA wood glues fail, including rubber, soft PVC, synthetic leather, and decorative laminates.
• Heat and Water Resistant: The cured film offers good resistance to moderate heat and water exposure, enhancing the longevity of bonded parts.

Key Features of Fevicol SR 998

• Synthetic Rubber Base: Solvent-based formulation ensures superior wetting and strong adhesion to difficult materials.
• High Coverage: Spreads efficiently, offering economical usage for large surface areas.
• Toluene-Free Formulation: A safer, less hazardous solvent profile compared to older contact adhesives.
• Durable Film: Creates a tough, permanent bond that withstands flexing and temperature fluctuations.

Recommended Application Areas

This contact adhesive is essential for:

• Automotive Interiors: Bonding foam, fabric, and synthetic leather for seating and trim.
• Footwear & Leather Goods: Durable bonding in shoe manufacturing and leather repair.
• Laminate Edge Banding: Professional application of PVC and laminate strips to furniture edges (cabinets, wardrobes).
• Flooring & Carpeting: Fixing rubber or synthetic flooring materials in commercial settings.

How to Use Fevicol SR 998 (Contact Bonding Technique)

Use in a well-ventilated area. Wear appropriate gloves and eye protection.

1. Surface Preparation: Both substrates must be clean, dry, and free from oil or dust. Abrade (roughen) surfaces like metal or rubber slightly with sandpaper for best adhesion.
2. Application: Apply a thin, uniform coat of Fevicol SR 998 to *both* surfaces to be bonded. Allow the solvent to flash off for 5-10 minutes until the adhesive film feels tacky (but not wet).
3. Assembly: Align the two coated surfaces perfectly and press them together firmly. This is a contact bond—alignment must be precise, as repositioning is difficult. Use a roller or hammer to apply brief, high pressure across the entire surface. Ensure surfaces are clean before applying contact adhesive.
4. Curing: The bond is strong immediately but achieves full chemical resistance after 24 hours. Clean excess adhesive with a solvent like toluene or **thinner**.

Frequently Asked Questions (FAQ)

Q: Do I need to clamp surfaces with Fevicol SR 998?
A: Generally, no. A brief, firm pressure is usually sufficient as the adhesive bonds instantly upon contact.

Q: What is the difference between Fevicol SR 998 and Fevicol SR 505?
A: SR 998 is often used for more demanding, heavy-duty industrial applications, offering superior strength, while SR 505 is popular for lighter domestic and furnishing purposes.

Q: Can this be used for wood-to-wood bonding?
A: While it can, for standard wood-to-wood bonds, a PVA glue like Fevicol SH is typically preferred due to its filling capabilities and non-solvent nature.
