With over 40 years of experience in the adhesives business – Cattie Adhesives is a trusted leader in the manufacturing of bulk industrial Foam Fabricating Adhesives. For over 40 years, Cattie Adhesives has met the ever-changing demands of the Foam Fabricating and Mattress Assembly industries.
Our acoustical Panel adhesives are designed to bond various fabrics to fiberglass panels and other insulating materials.
We also make an Edge Hardening Polymer that is used for application to fiberglass panels.
Edge hardener applications normally require 2 coats of polymer to insure proper edge hardness.
Our 100% water-based polymer can be applied to the edges of the fiberglass panels by roller, dipping or airless spray equipment.
| Problem | Possible Cause | Suggested Solution |
|---|---|---|
| Stringing | Application temp. too low | Raise application temp. DO NOT exceed recommended application temp. |
| Viscosity of adhesives is HIGH | Raise application temp. DO NOT exceed recommended application temp. | |
| Substrate is too far from applicator tip. | Position substrate closer to tip. | |
| Substrate temp. is too cold | Pre-warm substrate to increase surface temperature. | |
| Poor nozzle shut off | Clean Nozzle and repair. If problem persists, contact equipment manufacturer. | |
| Charring/Gelling in Reservoir | Reservoir temp. too high | Lower reservoir temperature |
| Faulty heating control | Check control and replace | |
| Surface oxidation | Maintain level of adhesive in reservoir. Keep reservoir covered; with some adhesives, nitrogen blanket may be necessary. | |
| Dripping Nozzle | Worn needle or seat | Replace |
| Nozzle dirty | Clean or replace | |
| Air in Adhesive at Applicator Tip | Extrusion head faulty | Consult with the manufacturer for a recommendation |
| Reservoir is out of adhesive. | Bleed lines and refill reservoir. Reset or replace valve. | |
| Poor Adhesion | Adhesive bond shows that the glue film is mostly on one surface which is caused by improper penetration of the secondary surface. | A) Apply heavier glue film and/or apply adhesive hotter. Sometimes both approaches are necessary.
B) In the case of very conductive surfaces (metals) the substrate may have to be preheated to assure proper penetration of the secondary substrate. |
| Bond failure shows adhesive on both surfaces with leggy strains.Usually caused by disturbing the Bond during the setting stage. | A) Check compression to assure that there is no shifting during adhesive set up.
B) Apply less adhesive. C) Lower adhesive Temperature. | |
| Poor penetration of substrate coating | A) Apply adhesive hotter.
B) Combine substrates quicker. C) Lower adhesive temperature. | |
| Glossy adhesive surface usually caused by poor contact with the secondary substrate. Temperature too low for proper wet out. | A) Adjust compression to assure intimate contact of substrates.
B) Increase adhesive temperature. | |
| Substrates Popping open | Hot melt is not cooling rapidly enough | A) Lower application temperature.
B) Decrease amount of adhesive applied. |
| Substrate is too hot to achieve proper cooling of adhesive | Cool substrates to room temperature if possible. |
