FAQ
-
Q
Bubbling of the glue joint
-
A
1. The base material is damp or there is rainwater in the adhesive joint;
2. The foam rods have a low density or are scratched, causing gas to escape.
3. The adhesive is applied too thin (less than 3mm) or there is a large temperature difference (high temperature in summer/low temperature in winter).
Solution: 1. Ensure the base material is dry and clean, and use closed-cell foam rods;
2. Avoid construction at noon in summer and choose the noon period (11:00-15:00) in winter.
3. It is recommended that the thickness of the glue joint be ≥6mm, and the ratio of width to depth be 1:2.
-
Q
The colloid cures too slowly
-
A
Low temperature (less than 5℃), low humidity (less than 40%) or poor ventilation.
Solution Improve the temperature and humidity of the construction environment (such as building a greenhouse).
-
Q
The colloid is cracked or poorly bonded
-
A
1. The base material is not cleaned (oil stains, dust) or compatibility tests have not been conducted;
2. The displacement of the joint exceeds the limit (for example, the designed joint is 20mm, but in reality it is only 5mm);
3. Low-temperature construction causes the colloid to be stretched by external force before it is fully cured.
Solution: 1. Clean the substrate and apply a primer to enhance adhesion;
2. Ensure that the size of the glue joint meets the design requirements and select glue with high displacement capacity.
-
Q
Colloidal surface particles or crusts
-
A
1. Improper storage of the colloid (curing upon contact with air);
2. After applying the adhesive, the surface was not adjusted in time, and the second operation was carried out after the surface dried.
Solution: 1. The colloid should be sealed and stored after opening.
2. The amount of glue mixed at one time should be used up within 20 minutes.
-
Q
Colloid discoloration (turning yellow, turning pink
-
A
1. Neutral transparent adhesive: Yellowing caused by amine crosslinking agents, or mixed with acidic adhesives;
2. Porcelain white adhesive: The titanium-chromium compound raw material temporarily turns red when exposed to high temperatures and returns to its original color after cooling.
Solution: 1. Avoid mixing adhesives of different systems and choose amine-free adhesives (such as ketoxime type).
2. The construction thickness should be no less than 3mm to minimize direct exposure to ultraviolet rays.
-
Q
The adhesive tape shrinks or wrinkles
-
A
1. Low-grade adhesives have more fillers, and the shrinkage rate after evaporation can reach 30%.
2. When applying adhesive to the vertical joints, the adhesive sagged and was not adjusted in time.
Solution Select Keda silicone sealant (with a shrinkage rate of less than 5%), and trim the edges from bottom to top when applying the sealant.
-
Q
Corrode the substrate (such as aluminium, mirrors
-
A
Acidic glue releases acetic acid, which can corrode copper, coated metals or the coating on the back of mirrors.
Solution Neutral adhesive is used for metal substrates, and alcohol-based neutral adhesive is selected for mirrors.
-
Q
The insulating glass fogs up (" tears"
-
A
Silicone sealant containing solvents penetrates butyl sealant, causing it to soften and flow.
Solution Use solvent-free silicone sealant to ensure that the butyl sealant completely seals the corners.
-
Q
Colloidal crystals or granules
-
A
Low-temperature storage leads to the precipitation of crosslinking agents (such as salt granular particles).
Solution Warm to room temperature before use, and the particles will dissolve automatically.
Preventive measures: 1. Substrate treatment: Conduct compatibility tests after cleaning. For metal substrates, avoid acidic adhesives.
2. Environmental control: Construction temperature: 5-40℃, humidity: 40-80%. Avoid rainy and snowy days.
3. Process Specifications: Before injecting the two-component adhesive, conduct the "butterfly test" and the "breaking test". 2) The trimming time should be controlled before surface drying (about 30 minutes for a single component). By standardizing material selection, strict construction and reasonable maintenance, the problems of silicone sealant can be significantly reduced. If the problem has occurred, local repairs or rework should be carried out based on the specific cause, and priority should be given to checking the compatibility of the substrate and environmental factors.
