ANPIN AP-688W(W123) White 300ml Flame-Retardant RTV Silicone Adhesive for PCB, PCBA and Electronic Components

ANPIN AP-688W W123 RTV Silicone 300ml is a white one-component room-temperature vulcanizing silicone adhesive designed for bonding, fixing, insulating and sealing electronic and electrical components. The AP-688 series provides fast surface drying, strong adhesion to common PCBA materials, electrical insulation, moisture resistance and flame-retardant performance for demanding electronic assembly applications.

Product Overview

ANPIN AP-688W(W123) belongs to the AP-688 family of industrial RTV silicone rubber adhesives manufactured by Shenzhen Anpin Silicone Material Co., Ltd.

The product uses a one-component condensation moisture-curing system. No separate catalyst, hardener or A/B mixing process is required.

When exposed to atmospheric moisture, the material gradually cross-links and cures into a flexible silicone elastomer.

During the curing reaction, small alcohol molecules are released as normal byproducts of the condensation process.

ANPIN AP-688W W123 RTV Silicone 300ml is supplied in a convenient cartridge format suitable for manual dispensing, production-line application and electronic component assembly.

Key Features and Advantages

Fast Surface Drying

ANPIN identifies rapid surface drying as one of the important characteristics of the AP-688 series.

Fast skin formation helps improve handling efficiency after component fixing and can reduce waiting time during electronic assembly.

Strong PCBA Material Adhesion

AP-688 provides strong adhesion to multiple materials commonly found in printed circuit board assemblies.

This makes the product useful for fixing capacitors, inductors, transformers, transistors and other components exposed to vibration or mechanical movement.

One-Part RTV Application

ANPIN AP-688W W123 RTV Silicone 300ml is ready to use directly from the cartridge.

Because no mixing process is required, the product is convenient for repetitive production and helps reduce errors associated with two-component adhesive systems.

UL94 V-0 Flame Retardancy

ANPIN lists the AP-688 family as meeting UL94 V-0 flame-retardant requirements.

This characteristic is particularly important for power supplies, lighting equipment, high-voltage components and electronic assemblies where flame resistance is required.

Wide Temperature Performance

The cured AP-688 silicone is specified by ANPIN for continuous operation from approximately -50°C to +200°C.

This broad operating range supports applications exposed to both low-temperature and high-temperature conditions.

Electrical Insulation

The cured silicone provides strong electrical insulation and high volume resistivity.

It is therefore suitable for protecting and fixing components in power supplies, inverters and other electronic equipment.

Moisture Resistance

AP-688 helps protect sensitive components against humidity and moisture after curing.

The flexible silicone layer can also help reduce mechanical stress caused by vibration and temperature cycling.

Flexible Elastomeric Cure

Unlike rigid structural adhesives, cured RTV silicone remains flexible.

This allows the adhesive layer to accommodate thermal expansion and movement between components and surrounding materials.

Applications of ANPIN AP-688W W123 RTV Silicone 300ml

PCB and PCBA Component Fixing

The product is suitable for securing electronic components mounted on printed circuit boards.

Typical components include capacitors, inductors, transformers and transistors.

Power Supply Assembly

ANPIN AP-688W W123 RTV Silicone 300ml can be used for bonding, fixing and insulating components inside AC and DC power supplies.

Inverters

The product is suitable for selected inverter components and high-voltage electronic assemblies requiring flexible insulation and component fixation.

LED Power Components

ANPIN specifically recommends the AP-688 family for fixing LED power components.

Lighting Equipment

The adhesive can be used in T8 lighting assemblies and other lighting products where secure and flame-retardant component fixing is required.

Industrial Electronics

The 300ml cartridge format is suitable for industrial production environments, electronic equipment assembly and repeated dispensing applications.

Important Technical Note

W123 is retained as the product suffix shown on the actual ANPIN product specification.

ANPIN’s public website currently provides technical information for the AP-688 family but does not publish a separate W123 technical specification table.

Therefore, exact W123-specific viscosity, density, tack-free time, Shore hardness, tensile strength and other numerical values should be confirmed using the latest TDS or product label supplied with the actual batch.
