Product Overview

ANPIN 905 is a two-part addition-cure silicone potting compound developed for electronic and electrical encapsulation.

The complete system consists of Component A and Component B. The two materials must be combined before curing and should not be treated as independent one-component products.

ANPIN 905 G30 Component A is supplied in gray and is intended to be paired with the corresponding 905 system Component B.

According to ANPIN’s current information for the 905 family, the two components are mixed at a 1:1 mass ratio and cure through an addition reaction to form a flexible silicone elastomer.

The cured material provides insulation, environmental protection and resistance to a wide range of temperatures.

Key Features and Advantages

Two-Part Addition-Cure Silicone System

ANPIN 905 uses addition-cure silicone technology.

Compared with condensation-cure materials, addition-cure systems generate very little shrinkage and do not rely on moisture penetration for deep-section curing.

This makes the 905 system suitable for potting relatively deep electronic assemblies.

No Significant Shrinkage or Exotherm

ANPIN states that the 905 system provides no significant shrinkage and no heat release during curing.

These characteristics are useful for sensitive electronic assemblies where dimensional stability and low curing stress are important.

Electrical Insulation

The cured silicone elastomer provides electrical insulation for electronic and electrical components.

This helps protect PCB assemblies, power supplies and electronic modules from electrical leakage and environmental contamination.

Waterproof and Moisture Protection

ANPIN 905 is designed for waterproof and moisture-resistant encapsulation.

After correct mixing and curing, the silicone forms a protective elastomer around electronic components and helps reduce exposure to humidity and water.

Wide Temperature Resistance

The official ANPIN 905 family information specifies a temperature resistance range of approximately -50°C to +200°C.

This allows the cured material to support electronic equipment used in changing low- and high-temperature environments.

Flame Retardancy

The 905 system is listed by ANPIN as UL94 V-0 flame retardant.

This makes it suitable for many electrical and electronic applications where flame-resistant potting material is required.

RoHS Compliance

ANPIN’s current product information also states compliance with the RoHS directive.

Applications of ANPIN 905 G30 Component A

LED Power Supply Potting

The 905 silicone system is commonly used for potting LED waterproof power supplies and internal LED driver assemblies.

PCB Encapsulation

When used together with the correct Component B, ANPIN 905 G30 Component A can form part of a protective silicone encapsulation system for printed circuit boards.

Inductors

The cured silicone helps protect inductors against moisture, dust and mechanical stress.

Sensors

The material can be used for sensor encapsulation where flexible environmental protection and electrical insulation are required.

Automotive Electronic Modules

ANPIN lists automotive electronic modules and electronic controllers among the applications for the 905 family.

Electronic Controllers

The material is also suitable for industrial electronic controls and other sensitive electrical assemblies that require potting protection.

Mixing and Application

ANPIN 905 G30 Component A must be used with the matching 905 Component B.

Before weighing, stir Component A thoroughly if any filler settling or separation is observed during storage.

For the standard ANPIN 905 family, the manufacturer specifies:

Component A : Component B = 1 : 1 by mass

Accurately weigh the required amount of both components.

Mix thoroughly until the material is uniform.

Avoid introducing excessive air during mixing.

Vacuum deaeration may be used when low-bubble encapsulation is required.

Pour or dispense the mixed material into the electronic assembly.

Allow the material to cure under the conditions specified in the current product TDS.

Because G30-specific public technical data is not currently listed on ANPIN’s website, users should confirm the mixing, cure and processing conditions on the actual product label or latest manufacturer TDS before production use.
