Resin solutions designed for stain and smell blocking interior paint
Increasingly, consumers and painters look for stain and smell blocking interior paints that are high in performance and low in emissions. Covestro designed NeoPac™ HP-5081 to meet this needs. As well as stain isolation – and smell blocking for NeoPac™ HP-5081 – both resin offers scrub resistance and formulation without coalescents.

“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.”

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.

Stain- and smell-isolating resin solutions for tomorrow’s interior wall coatings
By combining stain blocking with lower-emission ingredients, and high-performance properties, Covestro’s NeoPac™ HP-5081 stain-blocker resin helps meet multiple painting consumers’ needs. In this way, the resin can improve the possibilities for stain- and smell-blocking paints, primers, and coatings for interior walls.
Part of Covestro’s advanced coating resin technology toolbox
NeoPac™ HP-5081 is just one of many coatings solutions available in Covestro’s architectural resin technology toolbox. This toolbox includes waterborne acrylics, acrylic copolymers, acrylic emulsions, hybrids, tribrids, alkyds, urethanes, and partly plant-based resins.
Together, these solutions can enable high-performance coatings such as varnishes, aqueous paints, UV-curable paint, isolating paint, sealers, low-cure powder coatings, and more. These coatings can be used across multiple substrates in a range of interior environments, including high-moisture areas.
