Solvent-Free Butyl Hot Melt Sealant Factory | Sealant Manufacturers

Product Description

The Solvent-Free Butyl Hot Melt Sealant is a high-performance, environmentally responsible sealing solution designed for use in a wide range of industrial and construction applications. This advanced, non-curing hot melt sealant is made from refined butyl rubber and specialty tackifying resins—without the use of solvents or harmful additives. Its solvent-free formulation makes it safe, clean, and ideal for use in enclosed or sensitive environments such as hospitals, food facilities, and residential buildings.

When applied in molten form using hot-melt equipment, it sets rapidly upon cooling, forming a flexible, durable bond that delivers outstanding resistance to air, moisture, dust, and vibration. It offers excellent adhesion to various surfaces including metal, glass, plastic, wood, and concrete, all while maintaining its elasticity and sealing effectiveness over time.

Key Features

100% Solvent-Free: Free from volatile organic compounds (VOCs), making it safe for workers and the environment.

Non-Curing & Reusable: Remains permanently tacky and flexible, allowing for rework and repositioning.

Excellent Adhesion: Bonds strongly to aluminum, stainless steel, glass, PVC, wood, and other common materials.

High Sealing Integrity: Provides outstanding air, water, and dust sealing performance in indoor and outdoor environments.

Fast Processing: Hot-applied and quickly solidifies without curing time, reducing installation time and labor cost.

Odorless & Non-Toxic: Ideal for applications requiring clean air and low-emission materials.

Weather and UV Resistant: Suitable for use in areas exposed to sunlight, heat, and cold without degradation.

Typical Applications

Green Building Construction: Sealing window frames, curtain walls, and expansion joints in LEED-certified or eco-sensitive buildings.

Food Storage & Cold Chain Logistics: Used in sealing refrigeration equipment and insulated panels where VOC emissions must be avoided.

Automotive Interior Sealing: Ensures tight seals in door panels and instrument clusters without emitting odor or fumes.

Appliance Assembly: Provides clean, non-toxic sealing in household appliances like refrigerators and ovens.

Medical and Cleanroom Facilities: Suitable for controlled environments requiring solvent-free, low-emission materials.

Solar Panel Assembly: Seals module edges and backsheet panels without residue or long-term chemical migration.

FAQ (Frequently Asked Questions)

Q1: What does “solvent-free” mean for this product?

A1: It means the sealant is formulated without any organic solvents or VOCs, making it non-toxic, odorless, and safe for sensitive indoor environments.

Q2: Is it suitable for use in food or medical facilities?

A2: Yes. Its clean, non-toxic, and odor-free formulation makes it ideal for areas that require strict hygiene and low-emission materials.

Q3: How is this applied? Does it require special tools?

A3: It is applied in molten form using standard hot-melt equipment such as heated dispensers or glue guns designed for butyl sealants.

Q4: Will it harden or crack over time?

A4: No. This is a non-curing sealant that remains soft and flexible, even after long-term use. It accommodates movement and vibration without cracking.

Q5: Can it be painted over?

A5: Painting is not recommended, as the surface remains tacky and may not hold paint well. If aesthetics are critical, use the sealant in concealed areas or choose a color that matches your material.

Q6: Is it reusable or repositionable?

A6: Yes. As a non-curing adhesive, it can be reheated and repositioned if necessary, making it ideal for adjustable or modular systems.

Q7: What is the shelf life and how should it be stored?

A7: It has a 12-month shelf life when stored in a cool, dry area away from direct sunlight and heat. Always keep the packaging sealed to avoid contamination.
