Moisture/solids content significantly impacts the drying time, adhesion, curing, and longevity of paints, coatings, adhesives, and inks. Excessive moisture can lead to poor product performance, causing problems like delayed drying, blistering, cracking, or failure to adhere properly to surfaces. Insufficient moisture, on the other hand, can result in poor flow characteristics, premature drying, or improper curing. AMETEK Brookfield’s Computrac analyzers play a vital role in ensuring that moisture and solids levels are tightly controlled during production and application.
In packaging, inks must also be resistant to environmental conditions such as moisture and heat. Controlling moisture/solids helps ensure that inks dry quickly without compromising quality or adhesion, especially on flexible packaging materials.

Moisture/Solids Control in Paints and Coatings: In water-based paints and coatings, solids content directly affects the drying time and film formation. If solid levels are too low, the paint may take too long to dry, increasing the risk of dust or contaminants adhering to the wet surface. Excess solids can also result in defects like blistering, where trapped water vapor causes bubbles to form under the surface of the paint as it dries. AMETEK Brookfield’s Computrac analyzers allow manufacturers to precisely monitor the solid content in paints, ensuring that they dry uniformly and provide a smooth, durable finish.
In solvent-based coatings, moisture content must be carefully monitored to prevent unwanted chemical reactions, such as hydrolysis, which can degrade the coating’s quality. Brookfield’s Computrac analyzers help ensure that coatings meet the required performance standards, whether they are used in decorative applications or heavy-duty industrial environments.

Adhesives and Moisture Content: Moisture levels play a crucial role in adhesive performance, particularly in water-based adhesives. Too much moisture can weaken the adhesive bond, leading to reduced strength and increased curing times. Conversely, insufficient moisture can cause adhesives to set prematurely, making them difficult to apply or leading to improper bonding. Computrac analyzers are used to monitor the moisture content during adhesive production, ensuring the right balance for optimal bonding strength, curing speed, and flexibility.
In reactive adhesives like epoxies or polyurethanes, controlling moisture is essential to prevent unwanted curing reactions. Moisture can act as a catalyst in these systems, leading to premature cross-linking or bubbling, which compromises the adhesive’s performance. Brookfield’s moisture analysis tools help manufacturers monitor these processes, ensuring reliable adhesive performance in demanding applications such as aerospace, automotive, and electronics assembly.
- Inks and Moisture Balance: For printing inks, especially water-based or solvent-based systems, solids content directly influences drying speed, color consistency, and adhesion to substrates. In packaging applications, inks need to adhere to a wide range of materials, including plastics, paper, and metal, while resisting smudging or fading under environmental stress. AMETEK Brookfield’s Computrac analyzers help manufacturers maintain the proper moisture balance in inks, preventing issues like slow drying, tackiness, or print defects.
Controlling moisture/solids content is also critical in preventing inkjet nozzle clogging or uneven ink flow during high-speed printing processes. Accurate moisture analysis ensures that inks maintain optimal fluidity while drying quickly enough to meet production speeds without compromising quality.
Achieving Consistency and Performance: Moisture analysis is an essential component of process optimization for paints, coatings, adhesives, and inks. AMETEK Brookfield’s Computrac analyzers enable manufacturers to maintain consistent product quality by providing real-time data on moisture content throughout production. This helps reduce variability in batches, ensures faster production times, and minimizes waste due to defects such as improper curing, delayed drying, or bonding failures.
Environmental Control and Regulatory Compliance: Moisture content also affects the environmental impact of coatings, adhesives, and inks, particularly in industries where volatile organic compounds (VOCs) are regulated. By optimizing water-based formulations, which have lower VOC emissions, Brookfield’s moisture analysis tools help manufacturers produce environmentally friendly products that comply with regulations such as REACH, EPA standards, and other sustainability initiatives.
