Starting from the epoxy resin system, a fast-curing, low temperature-resistant epoxy resin was developed. Unlike adding accelerators to achieve rapid curing, modified adhesives avoid the pungent odor of accelerators and also have excellent mechanical properties.

Application Fields of Modified Epoxy Resin Adhesive

To improve the gluability and water resistance of soy-based adhesives, we prepared an enzyme-treated soy-based adhesive modified with an epoxy resin. We investigated the wet shear strength of plywood bonded with the modified adhesive using the boiling-water test.

In modern industry, epoxy resin adhesive is widely used due to its excellent adhesion properties, mechanical strength, and chemical stability. Modified epoxy resin adhesive is a product developed by adding specific modifiers to meet particular application requirements. This article introduces how to correctly use modified epoxy resin adhesive.

I. Preparation Work

1. Clean the Surface of Substrates

Use a clean cloth or cotton swab to remove dust, oil, and moisture from the surfaces to be bonded. Ensure the surface is free of contaminants, as this is essential for achieving optimal adhesion.

2. Clean the Work Environment

Maintain a dry, dust-free work area to prevent airborne particles from affecting bonding quality.

3. Prepare Bonding Tools

Use appropriate tools such as spatulas, brushes, or mixing sticks for applying the adhesive.

II. Mixing the Adhesive

1. Measure Proportions

Accurately measure the A component (resin) and B component (hardener) according to the recommended ratio (typically 4:1 (A:B)) specified in the product instructions.

2. Mix Thoroughly

Use an electric mixer or manual stirring rod to blend the components until fully homogeneous. If using an automatic mixer, follow the device’s operating guidelines.

3. Avoid Air Bubbles

Minimize air bubble formation during mixing. If bubbles appear, stop stirring immediately and remix thoroughly.

III. Applying the Adhesive

1. Apply the Adhesive

Spread the mixed adhesive evenly across the bonding surface. Maintain appropriate thickness, as excessive or insufficient layers may compromise bonding performance.

2. Application Order

For multi-layered or large-area bonds, start from the center and spread outward gradually to avoid uneven distribution.

3. Pay Attention to Corners and Edges

Apply adhesive carefully to corners and edges using a “dot-line-area” method: apply a small amount of adhesive at the corner, trace along the edge, then cover the entire surface.

IV. Curing Process

1. Waiting Time

Curing time varies based on materials and environmental conditions. Under room temperature, curing typically takes several hours to one day. Higher temperatures or humidity may shorten the process.

2. Avoid Movement

During curing, avoid applying external force, vibration, or movement to the bonded area.

3. Monitor Curing

Regularly inspect the adhesive for abnormalities such as whitening, softening, or bubbling. Discontinue use if issues arise.

V. Post-Treatment

1. Clean the Surface

After curing, remove excess adhesive and residues using solvents like alcohol or acetone. Avoid contact with uncured adhesive areas.

2. Inspect Bonding Quality

Test adhesion strength and integrity using methods like peel testing or impact testing.

3. Store Unused Adhesive

Store leftover adhesive in a cool, dry place, away from direct sunlight and high temperatures, to maintain stability.

VI. Precautions

1. Safety First

Wear personal protective equipment (PPE) such as gloves and goggles when handling chemicals.

2. Environmental Protection

Avoid contact between adhesive and food/beverages. Do not ingest or allow skin exposure to unused adhesive.

3. Eco-Friendly Choices

Select environmentally friendly adhesive products to minimize ecological impact.

proper use of modified epoxy resin adhesive enhances bonding efficiency and quality while extending material lifespan. Adjust application methods based on specific needs to achieve optimal results.
