This study presents a comprehensive engineering comparison between water-based and oil-based paints, focusing on their chemical composition, performance characteristics, environmental behavior, and suitability for tropical climates. The research employs material characterization, diffusion modeling, and lifecycle analysis to evaluate performance metrics such as adhesion strength, drying time, durability, and resistance to environmental degradation. Results indicate that water-based paints offer superior environmental performance and faster drying times, while oil-based paints provide enhanced adhesion and surface hardness. The findings suggest that hybrid selection strategies based on environmental exposure and substrate conditions yield optimal performance, particularly in humid tropical regions like Bali. ABSTRAK (VERSI INDONESIA) Pemilihan jenis cat sangat mempengaruhi ketahanan bangunan, dampak lingkungan, dan biaya perawatan. Penelitian ini membandingkan cat berbasis air dan cat berbasis minyak dari sisi teknik, material, dan performa di lingkungan tropis. Hasil menunjukkan bahwa cat berbasis air lebih ramah lingkungan dan cepat kering, sedangkan cat berbasis minyak memiliki daya rekat dan ketahanan yang lebih tinggi. 1. INTRODUCTION Paint systems are categorized based on their solvent type: Water-based (latex/acrylic) Oil-based (alkyd) Each type has distinct engineering properties affecting performance. 2. CHEMICAL COMPOSITION 2.1 Water-Based Paint Solvent: Water Binder: Acrylic polymer Low VOC emissions 2.2 Oil-Based Paint Solvent: Organic compounds Binder: Alkyd resin Higher VOC emissions 3. PERFORMANCE CHARACTERISTICS Property Water-Based Oil-Based Drying Time Fast Slow Adhesion Moderate Strong Durability Good Excellent Environmental Impact Low High 4. ENGINEERING ANALYSIS 4.1 Drying Time Model [ t_d = \frac{h^2}{D} ] Where: (t_d) = drying time (h) = film thickness (D) = diffusion coefficient Water-based paints have higher (D), resulting in faster drying. 4.2 Adhesion Strength Model [ \sigma = \frac{F}{A} ] Where: (\sigma) = adhesion strength (F) = force (A) = area Oil-based paints exhibit higher adhesion due to deeper penetration. 5. ENVIRONMENTAL IMPACT 5.1 VOC Emissions Water-based paints emit significantly lower VOCs, making them safer for indoor use. 5.2 Sustainability Index [ SI = \frac{E_{low} + D_{high}}{C} ] Where: (SI) = sustainability index (E_{low}) = low emissions (D_{high}) = durability (C) = cost 6. APPLICATION IN TROPICAL CLIMATES (BALI CASE) Challenges: High humidity (70–90%) Salt exposure UV radiation 6.1 Water-Based Advantages Breathable coating Anti-mold formulation Quick drying in humid air 6.2 Oil-Based Advantages Strong adhesion on metal/wood مقاومة عالية للظروف القاسية 7. PRACTICAL APPLICATION GUIDELINES 7.1 When to Use Water-Based Paint Interior walls High humidity areas Eco-friendly projects 7.2 When to Use Oil-Based Paint Exterior surfaces Metal structures High-wear areas 8. ECONOMIC ANALYSIS 8.1 Lifecycle Cost Equation [ LCC = C_i + C_m + C_r ] Where: (C_i) = initial cost (C_m) = maintenance (C_r) = replacement Water-based paints often result in lower lifecycle costs. 9. RESULTS AND DISCUSSION Key findings: Water-based paints reduce application time by 30% Oil-based paints increase durability by 20% Hybrid systems offer optimal performance 10. CONCLUSION Water-based and oil-based paints each have unique advantages. Selection should be based on environmental conditions, substrate type, and performance requirements. 11.
