CEMEDINE SX720W AX-207 333ml Flame-Retardant Elastic Adhesive for PCB Components and Electronic Sealing

CEMEDINE SX720W Cartridge Adhesive is a one-component white elastic adhesive designed for electrical and electronic component fixing, insulation and waterproof sealing. The AX-207 333ml cartridge format is suitable for production-line dispensing and industrial assembly applications requiring controlled and efficient adhesive application.

Product Overview

CEMEDINE SX720W AX-207 is part of the SX720 series of flame-retardant elastic adhesives developed for electrical and electronic equipment.

The product uses an acrylic-modified silicone resin system and cures at room temperature through atmospheric moisture. No separate hardener or mixing process is required, helping simplify production and reduce preparation errors.

The white paste has a viscosity of approximately 42 Pa·s at 23°C, allowing good flow around electronic components while maintaining sufficient bead control.

The 333ml cartridge configuration is designed for use with a compatible cartridge dispensing gun, making it particularly suitable for repetitive industrial production and controlled sealing work.

Key Features and Advantages

UL94 V-0 Flame-Retardant Performance

CEMEDINE SX720W Cartridge Adhesive is UL94 V-0 recognized and is suitable for electronic and electrical assemblies where flame-retardant performance is required.

One-Component Moisture Cure

The adhesive cures by reacting with moisture in the air at room temperature. No weighing, mixing or separate curing agent is required.

This one-component system helps improve manufacturing efficiency and reduces the possibility of mixing errors.

Siloxane-Free Formulation

SX720W is formulated without low-molecular-weight cyclic siloxanes, making it suitable for sensitive electronic applications where contamination control is important.

Flexible Bonding Performance

After curing, the adhesive forms a flexible elastic layer that helps absorb vibration, mechanical movement and thermal expansion between different components.

Fast Initial Strength Development

The formulation develops initial strength quickly while providing reliable long-term durability for professional electronic assembly.

Applications

PCB Component Fixing

CEMEDINE SX720W Cartridge Adhesive is suitable for securing capacitors, coils and other components on printed circuit boards.

Its elastic cured layer helps stabilize components while absorbing vibration and mechanical stress.

Transformer and Power Supply Sealing

The adhesive can be used for insulation sealing around transformers, power supplies and related electrical assemblies.

Electronic Waterproof Sealing

SX720W is suitable for waterproof sealing around electronic components, cable entries, electrical housings and industrial electronic modules.

Industrial Electronic Assembly

The product can also be used in control systems, electrical equipment and manufacturing applications requiring flexible flame-retardant bonding.

Suitable Applications

Typical applications include:

PCB component fixing
Capacitor reinforcement
Coil fixing
Transformer insulation sealing
Power supply sealing
Electronic waterproof sealing
Electrical enclosure sealing
Industrial control equipment
