The performance of SPUR+ PSA 3.0 is far superior to traditional rubber and acrylic pressure sensitive adhesives. SPUR+ PSA 3.0 can be applied using traditional PSA coating equipment and cured to thermally sensitive films to provide a highly tacky, chemical resistant, and weather stable adhesive layer that bonds well to low energy surfaces. SPUR+ PSA 3.0 is the ideal pressure sensitive adhesive for tapes and labels used in aerospace, automotive, medical, floor marking, and chemical labeling applications due to its outstanding resistance to solvents, moisture, and temperature. The features an benefits offered by SPUR+ PSA 3.0 are listed below:
- Useful over a wide temperature range and up to 356 °F
- Resistant to gasoline, jet fuel, diesel, brake fluid, hydraulic fluid, xylene, acids, bases, and various other solvents
- Good adhesion to polyolefins and other low energy surfaces
- Curable on thermally sensitive films
- Resistant to UV and oxidation from weathering
- Perfect balance of peel and tack
- Compatible with fillers for cost reduction
Where is SPUR+ PSA 3.0 Used?
SPUR+ PSA 3.0 is the ideal pressure sensitive adhesive for applications that require best in class solvent and chemical resistance. To highlight performance in harsh conditions, Momentive performed a comparison study with SPUR+ PSA 3.0, a solvent acrylic adhesive, and a silicone adhesive. The chemical resistance of the three adhesives are summarized below:

How to Apply SPUR+ PSA 3.0
SPUR+ PSA 3.0 is packaged at a viscosity that is suitable for use with standard tape coating equipment. If the viscosity or solids content needs to be adjusted it can easily be diluted with ethyl acetate, butyl acetate, MEK, MIBK, or other common solvents. The adhesive can be applied to the substrate with conventional tape coating techniques or by use of a brush or roller. Once applied, the solvent must be removed and the adhesive cured. Curing can be done at ambient temperature or if more rapid cure is required heat can be applied up 150°C. Once cured the adhesive can be bonded to the intended surface or a release liner can be applied in order to protect the adhesive layer for future use.
Conclusion Traditional solvent based acrylic and silicone pressure sensitive adhesives lack the chemical and solvent resistance needed for high performance industrial tape and label applications. In addition, many manufacturing processes can benefit from a contact adhesive that forms chemically resistant bonds to high and low energy substrates. SPUR+ PSA 3.0 offers best in class chemical resistance with a optimum balance of peel and tack that makes it an ideal adhesive for applications that require an adhesive to bond to multiple substrates and withstand harsh chemicals.
