Most water-based, single-component paints tend to soak up moisture over prolonged exposure. This often leads to a white cloudiness that fades once the paint dries, potentially leaving lighter stains on the affected area.
Our RBP-1 and RCL-1 formulations absorb moisture while preventing it from penetrating deeper into the Resysta material. Once dry, any stains significantly reduce, leaving barely noticeable traces. Importantly, these formulations maintain their adhesion, even when wet. This “wet adhesion” is a standout feature, as other coatings under similar conditions tend to show more haze during exposure and more visible stains after drying.
For best results, apply RBP at 40-60 g/m2 and RCL at about 60-80 g/m2.
As previously stated, both coatings use highly light-stable acrylic resins and include a light stabilizer that blocks harmful UV rays, preserving the surface.
The choice of pigments is crucial. Our coatings, especially those with transparent iron oxides like the walnut shade, excel in UV absorption while remaining unaffected by the light, offering superb protection.
Both laboratory and natural outdoor tests reveal that the gloss level diminishes over time.
The accompanying photos show a comparison of parts with different pigments after undergoing the Arizona test. The left panel is unexposed and untested for each set, while the right panel has been exposed. The first image displays the walnut shade, followed by a photo showing the unpigmented structure.
The subsequent photo demonstrates the impact of the integrated light stabilizer. These parts underwent testing in a QUV-B 313 nm device. The left sample lacks a light stabilizer, whereas the right samples contain 1%, 2%, and 3% light stabilizer, respectively.
Observations also reveal enhanced durability in the portion primed with RBP.
Over time, despite these protective measures, the paint system will naturally degrade due to exposure. This includes a loss of shine and potential color changes. However, the paint can be reapplied using the same material to refresh weathered surfaces.
On the next picture you can see the effect of the built-in light stabilizer. The parts were tested in QUV-B 313 nm device. On the left is the zero sample without light stabilizer, on the right are the samples with 1%, 2% and 3% light stabilizer.
It can also be seen that half of the part that was primed with the RBP had somewhat better durability.
Despite all the measures, the paint system will weather over time depending on the load. One must reckon with the loss of sheen and the change in color, depending on the load. The paint structure can be overpainted, and the same material can be used to renew the weathered surfaces.
The Resysta Color Concept offers an exceptional chance to craft captivating projects with over 30 colors. We take pride in being the sole provider of a composite product in the market that can be custom-refinished to meet our customers’ color preferences.
Resysta RBP Primer is a water-based, clear primer made from acrylate dispersion. It provides strong adhesion, seals the surface to prevent water ingress, and ensures smooth application of the transparent-colored Resysta RCL stain. It’s an ideal choice for preparing surfaces and is suitable for indoor and outdoor use.
The RCL finish is a water-based, single-component protective stain tailored for adding color to Resysta surfaces. It’s perfect for indoor and outdoor applications, boasting excellent weather and water resistance. This finish is primarily used for decorative color styling on Resysta facades, decking, and roof soffits.
