It is crucial to choose a suitable adhesive for repairing when the acrylic board breaks. Here are some commonly used adhesives and their usage precautions:

Common adhesives

UV glue: UV glue can quickly cure under UV irradiation, making it suitable for situations that require quick repair. However, it is necessary to ensure sufficient exposure to ultraviolet radiation during use, otherwise it may affect the curing effect.

Acrylic Shadowless Adhesive: This adhesive is specially designed for acrylic materials, with good bonding effect, excellent flexibility, and is not easy to crack after curing. It is also resistant to high and low temperatures. Its rapid solidification characteristic also improves the repair efficiency.

Epoxy AB adhesive: Epoxy AB adhesive is made by mixing two components and has excellent adhesive properties and chemical resistance. It is suitable for repair work that requires a certain level of strength.

Methyl methacrylate (MMA) adhesive: This adhesive is specifically used for bonding acrylic, with strong adhesion and transparency, fast curing process, and suitable for bonding acrylic of various thicknesses.

Acrylic adhesive: usually a two-component adhesive with strong adhesion and good weather resistance, suitable for outdoor environments or long-term stable repairs.

Precautions for use

Clean the surface: Before bonding, be sure to use a mild cleaning agent and a soft cloth to remove any stains, oil stains, dust, etc. from the surface of the acrylic board. If the surface is not clean, bubbles are prone to appear after bonding, which affects the bonding effect.

Polishing treatment: Lightly polishing the surface that needs to be bonded can increase adhesion. After polishing with fine sandpaper (such as 320 grit), clean it promptly to remove any dust generated.

Uniform application: When bonding, ensure that the amount of glue used is even and not too much or too little. Too much can affect aesthetics and be difficult to remove; Insufficient amount may cause the adhesive to enter the air during shrinkage, affecting its adhesion.

Avoid direct sunlight: Before the adhesive is fully cured, try to avoid direct sunlight to prevent the adhesive from turning yellow and affecting the aesthetics of the acrylic board.

Good ventilation: Some adhesives may release harmful gases during use, so they should be operated in a well ventilated environment and protective equipment such as gloves and masks should be worn.

Curing time: Different types of adhesives have different curing times. During use, avoid moving the adhesive parts within the curing time to avoid affecting the bonding effect.

Inspection and adhesive repair: After the bonding is completed, the bonding effect can be checked by gently applying pressure or vibration. If local looseness is found, it can be repaired with adhesive appropriately.

In summary, choosing the appropriate adhesive and following the correct operating steps are the key to repairing shattered acrylic sheets. During the operation, it is essential to pay attention to safety and follow the instructions in the product manual.
