Shin‑Etsu Primer No.34T Adhesion Promoter 1 kg Silicone Primer for Metal, Glass & Plastic Surfaces

About Shin-Etsu Primer No.34T

OVERVIEW:

Shin-Etsu Primer No.34T is a specially formulated adhesion promoter designed to improve the bonding performance of RTV (Room Temperature Vulcanizing) silicone sealants and adhesives to various substrates. It enhances adhesion to difficult-to-bond surfaces such as metals, glass, ceramics, and some plastics, ensuring stronger, more durable bonds. Primer No.34T is commonly used in construction, electronics, automotive, and general industrial applications where improved silicone adhesion is required.

KEY FEATURES:

Adhesion Promotion
Enhances bonding strength between RTV silicone products and substrates that are typically challenging for silicone adhesion.

Broad Substrate Compatibility
Improves adhesion to metals, glass, ceramics, and certain plastics, supporting versatility in application.

Fast Drying
Dries quickly at room temperature, allowing for efficient processing and reducing waiting times in production.

Improves Bond Durability
Contributes to long-term bond strength and resistance to environmental factors such as moisture and thermal cycling.

Ease of Application
Can be easily applied by brush, spray, or dipping methods, supporting flexibility in manufacturing and maintenance operations.

APPLICATIONS:

• Construction and Building – Used to enhance adhesion of silicone sealants on curtain walls, glass panels, and metal frames.

• Electrical and Electronic Components – Improves bonding of silicone encapsulants and sealants to housings and components.

• Automotive Assembly – Applied to promote adhesion of silicone gaskets and sealants in engine compartments and body components.

• General Industrial Use – Suitable for bonding silicone materials to metal, glass, and ceramic surfaces in diverse industrial applications.

PACKAGING:

Shin-Etsu Primer No.34T is typically supplied in containers such as 1L cans or larger packaging (e.g., 15L) depending on regional availability and application requirements.

INSTRUCTIONS FOR USE:

• Surface Preparation: Clean surfaces thoroughly to remove dust, oil, grease, and other contaminants that may interfere with adhesion.

• Application: Apply a thin, even layer of Primer No.34T to the target surface using a brush, spray, or dip method. Allow the primer to dry completely (typically at room temperature) before applying the RTV silicone.

• Curing: Once the primer has dried, proceed with the application of the silicone adhesive or sealant according to product instructions.

SAFETY AND HANDLING:

Shin-Etsu Primer No.34T contains organic solvents and should be used in a well-ventilated area. Avoid contact with eyes and skin. Use appropriate protective equipment such as gloves and goggles. Keep away from open flames and sources of ignition. Refer to the product’s Safety Data Sheet (SDS) for complete safety, handling, and disposal guidelines.
