Montana Plastic Primer is the perfect pre-treatment for plastic surfaces. After priming and drying, plastic surfaces can be painted with Montana sprays that have a synthetic, acrylic, or nitro-combination base. Can be used with the following types of plastic: polypropylene rubber, modified (EPDM), Acrylic Butadiene Styrene Plastics (ABS), Glass-Fibre Reinforced Plastics (GfK), Hard Polyvinyl Chloride (Hard-Pvc), Polyurethane (PUR), Polystyrene (PS), Polyamide (PA). It is recommended to test before use. Drying time varies depending on temperature and humidity and may take a few hours.
USE: Apply primer in several thin layers spraying before the previous coat is fully dry, but with 1 or 2 minutes between each pass. Further coats might require a drying time of 24 hours or more depending on substrate. Always test spray on a non-visible area to check compatibility of lacquer or paint.
When should I use a primer?
The goal of priming is to create a neutral surface of which to apply other coatings onto that will have the longest possible lifespan and the most aesthetic finish as desired. Montana Primers are for the pre-treatment and preperation of surfaces and will offer the greatest adhesion and protection to apply further coatings onto.
When do I use Montana PLASTIC PRIMER?
The Montana PLASTIC PRIMER is ideal for preparing plastic materials for the application of color coats to assist in adhesion and reducing the risk of tearing and cracking. Montana PLASTIC PRIMER is a surface preparer that can be used on the following hard plastics: polyurethane (PUR), polystyrene (PS), polyamide (PA), polypropylene rubber, modified (EPDM), acrylic butadiene styrene plastics (ABS), glass-fibre reinforced plastics (GfK), hard polyvinyl chloride (Hard-PVC).
Will my Montana PLASTIC PRIMER work with all plastics?
Although suitable for many plastics, due to the varied chemical make up’s of some plastic and acrylic surfaces, some materials will not allow any paints or coatings to adhere. We suggest trialing on a non-visible area of your material to test for compatibility.
What do I need to watch out for when working with plastic based materials?
When using plastic materials, always be aware of expansion and contraction. This occurs through exposure to heat and cold. If your substrate expands in heat or contracts in cold beyond that of the flexibility of your coatings, then cracking, peeling or tearing will occur regardless of pre-treatment. Some plastic based materials are manufactured for particular functions. Their chemical make up may not allow any coatings to be applied. Keep your coated objects away from extreme heat/cold and direct sunlight to extend the lifespan of your project.
How do I start using my Montana PLASTIC PRIMER?
Remove the spray nozzle and turn the can upside down. Strike with your palm allowing safety ring to fall out. Shake vigerously for 2-3 minutes ensuring you can hear the mixing balls moving freely. Replace the cap back onto the top of the can valve and trigger away from substrate to test. If flowing freely you can start painting.
Which coatings can apply over the PLASTIC PRIMER?
You can apply any Montana-Cans color, tech or effect spray over the PLASTIC PRIMER once it has dried. It will increase adhession, help seal your substrate, create a more even surface and increase the longevity of the coatings applied over it.
How long does Montana Montana PLASTIC PRIMER spray take to dry?
Drying time is usually 15-20 minutes to be dust dry but can vary depending on substrate, ambient temperature, humidity levels and thickness of coats applied. Painted objects should be left to dry for 24-48 hours to cure.
Can I use other coatings on it other then sprays?
Yes. It is possible to use other coatings over PLASTIC PRIMER spray once it is dry. We suggest always test on a non-visible area of the work for compatibility.
