The need for more functional stain- and smell-blocking coatings

When painting their interior walls, today’s decorative paint consumers increasingly look for solutions that can resist and isolate stains or smell.

Stain- or smell-blocking interior paint allows these consumers to cover stains or smells efficiently when painting, without the application of multiple layers to the wall surface.

These stain- or smell-isolating paints can be applied as a wall primer, locking in the stain or smell to prevent bleed-through. After this, the primer only needs to be covered with one extra coat for a stain -free paint finish.

At the same time, consumers also seek decorative coatings with high-performance functional properties, such as good adhesion, chemical resistance, and high gloss. They also look for coatings with more natural ingredients, such as low-VOC paints.

To create these interior paints and primers, coatings manufacturers need resins that can isolate stains and smell well.

NeoPac™ HP-5081: Low-VOC, stain and stain & smell -blocking resins from Covestro

To address this need, Covestro created NeoPac™ HP-5081. We developed this  decorative primer resin to meet the need for stain isolation, more natural ingredients, and strong functional performance in paints and coatings for interior walls.

With the  ability to isolate a wide range of stains effectively,  NeoPac™ HP-5081 makes painting over pre-existing stains easier – whether the stains are from grease, oil, water, smoke, or nicotine. The resin can act as a stain blocker in interior paints, primers, or topcoats on a wide range of interior wall surfaces.

In addition, NeoPac™ HP-5081 can isolate smells, such as from tobacco, in pre-existing finishes.

NeoPac™ HP-5081 can also help you improve functional performance in your coatings. This  solution offers good mechanical and chemical resistance properties, and can be formulated to achieve scrub class 1. It is  also stable with colorants, enabling you to create a full range of color paints.

NeoPac™ HP-5081 can also  be made with a formulation that doesn’t use coalescents, enabling interior paints, primers, and topcoats that are very low in VOCs and odor. This also supports compliance with regulatory or labeling requirements.

“NeoPac™ HP-5081 enables Covestro’s coatings customers to create primer, paint, or topcoat solutions that offer stain or smell blocking, along with an improved emissions profile and high-performance properties. In turn, this makes painting over stains or smells – on a wide range of substrates and surfaces – much easier for end-users.”
