1. Lamp strip coating adhesive

The coating type glue generally requires a low viscosity (< 1000Cs is preferred) to facilitate spraying and brushing. Dealcohol-based two-component silicone rubber used for lamp strip coating exists in the form of transparent adhesive, many of which are volatile types, and the common ratio is 2:1 and 1:1. In use, first mix according to a certain proportion, and then spray on the lamp strip, playing the role of three prevention; Due to the application field, the product needs higher transparency and a certain strength, the conventional reinforcing powder can not be used, need to choose the appropriate resin reinforcing.

Basic formula: Component A mainly contains 107 silicone rubber, solvent, silicone oil and resin, etc. Component B is mainly crosslinking agent, coupling agent, catalyst, silicone oil and solvent (note: Component B should be sealed and stored to prevent its hydrolysis from affecting normal performance)

2. Electronic sealant

In recent years, dealcoholized two-component electronic bonded silica gel has gradually entered the market and been favored by the market due to its remarkable characteristics such as excellent adhesion and fast deep curing rate. This type of product is mainly used for bonding and sealing in places that need faster curing, such as headlights, fog lamps, household appliances, etc., the common ratio is 2:1, 1:1, and its A and B components are mainly in paste form or semi-flowing paste form, such as Huitian-HT-4061, etc.; There are also some other special proportions, such as Silicon Treasure 662, 1062 fog lamp sealant, is (10-12) :1, Dow (Dow Corning) 3636 lamp adhesive is 100:13 (5.9:1).

Basic formula (1:1) : Component A mainly consists of 107 silicone rubber, powder, silicone oil and catalyst. Component B mainly consists of 107 silicone rubber, powder, silicone oil, crosslinking agent and coupling agent.

Dealcohol-based two-component adhesive silica gel environmental protection, non-corrosion, excellent adhesion, fast deep curing rate and other advantages, making it more and more widely used in the field of electronic industry, especially 1:1 or 2:1 ratio can be packaged easily, 50ml(25+25), 400ml(200+200) this common packaging form of the market makes the use of two-component adhesive seal bonding as convenient and simple as a single component, the market share will be more and more high.

Through the above brief introduction of several common types of dealcohol-based two-component silicone rubber, we can find that this type of product is still relatively large in the market, both used in the construction industry, but also used in the electronics industry, can be used for sealing, sealing, can be fluid, but also semi-flowing, paste. R&d and engineering personnel can prepare different types of dealcohol-based two-component silicone rubber according to different application projects and customer needs; More attention should be paid to the improvement of storage and adhesion, and the transparency of transparent glue type should also be paid attention to.
