Technical Details & Test Data
- Compatibility
It is compatible with many plastics, seals, PCB components, paints, rubbers, and plant fibers.
Substrate Compatibility: Consult the 824 compatibility chart for a tentative compatibility list. These compatibility ratings should be considered as tentative due to variations in plastic manufacturers’ formulations and additives, as well as the processing conditions during cleaning.Attention !
Always perform a compatibility test on a non-critical area or a representative test substrate prior to use. Test even if the compatibility chart predicts a high compatibility: modern parts may incorporate undeclared sensitive materials (such as custom plastic blends, custom additives, protective coatings, or decorative coatings).
824 Plastics Compatibility Chart
Plastic type Resistance Epoxy Excellent ABS (acrylonitrile butadiene styrene) Fair to Poor PMMA (acrylic and plexiglass) Poor PVC (polyvinyl chloride) Excellent HD-PE (high density polyethylene) Excellent LD-PE (low density polyethylene) Excellent PP (polypropylene) Excellent PS (polystyrene) Excellent PC (polycarbonate) Excellent Nylon Poor to Severe Note : Rating is given for room temperature only. Heating the solution generally decreases the chemical resistance.
LEGEND
- Excellent = Negligible chemical attack over long exposures
- Good = Slight attack with minor absorption over long exposures
- Fair = Moderate attack with swelling, softening, loss of strength (may tolerate short term exposures)
- Poor = Not recommended due to possible crazing, cracking, discoloration, or loss of strength
- Severe Effect = Decomposition or dissolution after short exposures

Heating the solution generally decreases the chemical resistance.
Attention !
Do NOT use on computer monitors, tablet screens, or eyeglasses. This solvent is too powerful for the coatings used on these devices.
