FAQs

1. Why choose ExceedChem adhesive to replace Chemlok, Cilbond and Rohm Haas etc?
ExceedChem adhesive focuses on research and developing rubber to metal bonding adhesive for decades.Our main purpose is to replace world brands like Chemlok, Cilbond and Rohm Haas to offer customers alternative choice with better quality and more competitive price. Of course, there are still types which we can not replace. However, ExceedChem is always on the way with customers to move forward.

2.What are the four stages of the ExceedChem bonding process?
1. Substrate preparation
2. Primer, adhesive application
3. Elastomer preparation
4. Molding, curing and finishing

3.What are the drying processes for ExceedChem solvent-based adhesives?
A. All ExceedChem solvent-based adhesives can be dried at room temperature, from 30 to 60 minutes at 24°C (75°F). If faster drying is necessary, use a circulatory air dryer at 65°C (150°F) to 93°C (200°F). Humidity plays an important role in the drying process. Extended dry times are required where humidity levels are high.

4.How long does the ExceedChem adhesive need to dry before molding?
A. The dry time varies for each ExceeChem adhesive and is dependent on the type and amount of solvent carrier and its evaporative rate. Other influences are the dry film thickness, method of adhesive application, as well as plant conditions such as air flow, humidity and temperature. Typically, most ExceedChem adhesives will dry in one hour at ambient temperature.

5.What safety precautions are recommended when using ExceedChem adhesive?
1. Keep application and storage areas ventilated and free of ignition sources.
2. Wear protective clothing as needed.
3. Keep work and storage areas clean.
4. Clean application equipment regularly.
5. Dispose of waste according to country and local regulations.
6. Read labels, MSDS and product bulletins before using.

6.How much ExceedChem adhesive do I apply to the substrate?
A. The key is to apply ExceedChem adhesives in a uniform, consistent manner that deposits a continuous dry film free of runs, sags or drips. To determine optimal dry film thickness, bond testing should be performed to decide how much adhesive should be applied for each individual application. Keep in mind that dry film thickness does affect bond quality. Typically, primers require 0.2 to 0.4 mils, while covercoats require 0.3 to 0.5 mils, and one-coat adhesives 0.7 to 1.0 mils.
