High Solid Polymer Dispersions

Available On-demand (originally presented November 8, 2021)

The performance of water-based architectural paints has steadily improved over the last few decades, and water-based products have pretty much replaced oil-based paints in architectural coatings. Although there has been great progress in lowering the VOC demand and improving the final film properties of water-based paints, there are still opportunities to improve water-based systems. Binders in water-based paint systems are typically limited to 40–50% polymer solids content and higher solids polymer dispersions would open new formulation spaces. For example, a higher solids polymer dispersion would allow formulation of paints with higher volume solids, more Newtonian rheology behavior and more desirable application properties similar to traditional oil-based products. Further, higher solids polymer dispersions could potentially reduce freight cost and/or storage tank capacity. Here we present advances in producing high solid polymer dispersions and explore performance benefits specifically in architectural trim paint.

Low VOC Capable Acrylic Dispersion for Improved Metal Protection

Available On-demand (originally presented November 8, 2021)

Although solventborne or 100% solids technologies remain dominant for corrosion protection, due to increased regulations around VOC emissions, replacing solvent-borne systems with waterborne dispersions is an effective strategy for reducing VOC emissions. The industry has sought to improve the performance of waterborne systems to facilitate in this replacement. Our latest development emphasizes our commitment and expertise in this field.

This study demonstrates a high-performance, APEO- and zinc-free binder with improved corrosion protection compared to other 1-component waterborne binders of equivalent dry film thickness. This new resin helps to save formulation cost and complexity by decreasing or eliminating the use of active inhibitors. The versatility of this technology will be showcased by results in a high-gloss direct-to-metal (DTM) coating and primer. By balancing the hydrophobicity and chemical functionality, BASF has developed a resin with low water uptake, good early water and humidity resistance, and excellent corrosion resistance while still allowing for ease of formulation and pigment dispersion. This functionality also allows for superior adhesion to multiple substrates, including plastics. The self-crosslinking mechanism also ensures good block and chemical resistance. Lastly, low VOC formulations down to 50 g/L are capable without the use of plasticizers which can result in softening of the protective coating.

Bio Based Defoamer for use in Emulsion Polymerization, Coatings, Inks and Adhesives

Available On-demand (originally presented November 10, 2021)

In this talk we will present a new defoamer developed using bio-based raw materials that has extraordinary defoaming capability in emulsion polymerization, waterborne coatings, inks and adhesives. It has very broad, global, food contact ratings and is capable to be used for both indirect and direct food contact in coatings, inks and adhesives. It has long term stability and minimal separation characteristics as supplied. It is easy to handle and incorporate into formulas. It has effective performance in a broad range of polymers and types of inks, adhesives or coating formulas, so offers flexible use, reducing the need for multiple defoamers for the different markets.

Highly Effective Defoamer Package for Printing Packaging

Available On-demand (originally presented November 10, 2021)

A defoamer package composed of a wetting agent, and two defoamers with different chemistries is highly efficient in reduction of micro-foams. The defoamer package has shown synergistic effect by incorporating a wetting agent, a novel polymer-based defoamer, and a silicone-based defoamer. The defoamer package has demonstrated superior defoaming effect in traditional printing inks, over print gloss coatings.

Latex for High Gloss Paint

Available On-demand (originally presented November 11, 2021)

The challenges for low VOC waterborne high gloss paint is to provide a durable, hard matrix with good film formation attributes. By carefully designing the latex, BASF demonstrated that low VOC waterborne acrylic paint can be achieved with good balance of: (1) Low tackiness and good hardness; (2) Good scrub, stain resistance and other interior properties; (3) Low dirk pick up, good gloss retention for exterior application.

New Acrylic Polyol with Enhanced Performance for 2K PUR Direct to Metal Coatings

Available On-demand (originally presented November 11, 2021)

Corrosion protection has been one of the major challenges in the protective coatings market. 2K urethane coatings are commonly used in this market either as primers, topcoats, or direct-to-metal topcoats, however end users are increasingly demanding more corrosion protection with fewer coats.

Direct-to-metal coatings (DTMs) are advantageous in that multiple coating types and preparation techniques are reduced by applying a coating with adhesion and resistance properties, while maintaining the properties of desirable topcoats, like high gloss, hardness, and corrosion and chemical resistance.

BASF has developed an acrylic polyol suitable for low VOC solvent based direct-to-metal (DTM) 2K urethane coatings. This new resin has shown increased pot life, good dry and wet adhesion to various metal substrates, good corrosion resistance as measured in salt spray which is a key requirement for the protective coatings market that demands long service life.

Adhesion to Difficult Substrates

Available On-demand (originally presented November 12, 2021)

Substantial differences across substrate surface properties make it very difficult for architectural coatings to achieve superior multi-substrate adhesion. This challenge is further complicated by the need to balance adhesion with other important coating properties. BASF’s latest developments on emulsion polymers achieve this challenging goal, delivering a solution that improves the resilience of low-VOC coatings.
