Hard Coat requirements for Scratch resistance 硬质涂料 对耐刮擦性能 As a general “rule of thumb”, high cross-link density leads to improved scratch resistance. 按一般“经验法则”,高交联密度可增强耐刮擦性。 高Tg 则不一定能产生良好的耐刮擦性。 Generally high Tg – Tg does not lead to scratch resistance.  High functional aliphatic urethane acrylate and high functional monomers such as DPHA, Di-PEPA, Di-TMPTA, PETIA are typically used to give scratch resistance.  High functional materials are often brittle and can lose adhesion, due to shrinkage.  Dendritic acrylate gives high scratch resistance, toughness, low shrinkage and adhesion.  使用高官能度的脂肪族聚氨酯丙烯酸酯和高官能 度的单体(如 DPHA、Di-PEPA、Di-TMPTA 和 PETIA)都可获得较好的耐刮擦性。  高官能度的产品通常较为脆,并且会缩边而导致 附着性不好。  超支化丙烯酸酯具有良好的耐刮擦性、韧性、低 缩边和良好的附着性。

(BADGE DA has quite low scratch resistance)  DPHA和超支化丙烯酸酯的光泽度损失最小,耐刮擦性最好  BADGE DA的结果显示硬度不是实现耐刮擦性的唯一必要 条件 。(BADGE DA 的耐刮擦性极低)

UV ”Soft-feel” Requirements UV“柔感” 必要条件 1. Soft-feel / soft touch effect  Gives sense of luxury, high-quality and comfort  Described as haptic, soft-touch, silky-peachy etc…  Very subjective (a tactile perception)  Problem to qualify and quantify the effect. 1.     柔感 / 柔软触感效果 具有豪华、高品质的舒适感受 可称为触感、柔软手感、柔滑等形容词 非常主观的感觉(触觉) 难以对效果进行定性和定量。

UV ”Soft-feel” Requirements UV“柔感” 必要条件 2. Matt/ Gloss  Usually matt coatings – few hundred µm thickness 2. 哑光/高光泽度  一般为哑光涂料, 厚度为几百 µm 3. Resistance  Especially chemical & scratch resistance – often more difficult to achieve in matt 4. Adhesion  Multiple substrates, so normal requirements exist. 5.

Tg – Glass Transition Temperature Reversible transition from hard to “rubbery” state  Measured by DSC (Differential scanning calorimetry) or DMA (Dynamic Mechanical Analysis)  Primary Tg is most commonly applied to thermoplastic amorphous or semi-crystalline materials  Primary Tg is just one transition that can be measured in polymers  Sometimes called “a” transition, “b” transition etc. or “primary”, “secondary” etc.  The “a” transition is generally the true Tg for a thermoplastic material.  In highly cross-linked systems, the “b” or secondary transition measures rotations around and between cross-links. Tg – 玻璃化温度 由硬质到“弹性”状态的可逆转变  通过 DSC(示差扫描量热法)或DMA(动态力学分 析)测得  初级 Tg 最常用于无定形或半结晶热塑性材料  初级 Tg 仅仅是聚合物中可测的一次转换  有时被称作“a”转换、“b”转换等或“初级”、“次级”等  “a ”转换通常是热塑性材料的实际 Tg。  在高度交联的体系中,“b”或次级转换测量的是交联 体周围或交联体之间的旋转。 Mw between 2 crosslinking knots (Mc) Thermoplastic behaves like noodles 热塑性像面条:  Dry = solid 干=固体; 熟=移动  Cooked = mobile Thermoset is locked by cross-links  a little like knitted wool 热固性的交叉链接有点像针织的毛绒。

Tg – For UV Cured System Tg – 适用于紫外光 固化体系 Reversible transition from hard to “rubbery” state  UV cured systems are typically “thermoset” and cross-linked  High functionality to ensure good resistance properties  Functionality must not be too high or it will restrict transition  Low secondary transition Tg is desired to give soft feel  Too low Tg will reduce resistance properties  Linear molecular chains allows greatest control of Tg. 由硬质到“弹性”状态的可逆转变  紫外光固化体系通常为“热固性”和交联型  高官能度以确保良好的耐受性能  官能度不能过高而影响转换受到限制  低次级Tg可带来柔感  过低的 Tg 会降低耐受性  线性分子链可最大程度地控制Tg。

Why choose Capa™ ”Backbone”? 为何选择 Capa™ “骨架”? Characteristics associated with Oligomers based on Capa™  Flexibility ‒ Oligomers are flexible and tough.  Low Viscosity ‒ Oligomers typically show lower viscosity for equivalent Mwt.  Durability ‒ Exterior durability. ‒ High abrasion resistance.  Control of Tg. ‒ Possibility for “soft feel” 与基于 Capa™ 的低聚物相关的特性  柔韧性 ‒ 低聚物具有高弹性和高强度。  低粘度 ‒ 对比当量分子量,低聚物的粘度都低。  耐久性 ‒ 室外耐久性。 ‒ 高耐磨性。  Tg 的控制。 ‒ 可形成“柔感”

Capa™ Capa™ Monomer OHROH Catalyst Capa™ Polyol The reaction is “ring opening” “开环”反应  low temperatures, less catalyst and no water  低温,催化剂少且不生成水  clean polyester polyol, narrow Mw distribution and clearly defined functionality.  高纯度聚酯多元醇、较窄的分子量分 布和清晰界定的官能度。

Capa™ Polyols Capa™ 多元醇  Grades can be tailored depending on type of “initiator”.  “Initiator” has significant effect on properties.  可根据“起始剂”的类型进行分级。  “起始剂”对性能有显著影响。  Functionality of the “initiator” repeated in the polymer polyol, so di-, tri- and multi functional polyols can be produced.  “起始剂”的官能度能在聚合物多元醇中重 复出现,因此可生成二元、三元以及多官 能度的多元醇。 Capa 2 series – 200 – 8,000 Mw Diols Capa 3 series – 300 – 3,000 Mw Triols Putting the care into chemicals

Control of crystallinity 结晶度控制 1. Careful selection of “initiator” 2. Co-polymer modification of polyol 1. 精心挑选“起始剂” 2. 共聚物改性的多元醇 Reduction of crystallinity in oligomers based on Capa™ 低结晶的Capa™低聚物

Experimental 实验 Viscosity comparison (20% TPGDA) 粘度对比 Sample 1. = 1.1 Pas Sample 2. = 1.2 Pas Two samples were prepared for comparison; Both use 2,000 Mw caprolactone 制备两种样品用于对比; 均使用分子量为 2,000 的 Caprolactone(己内酯) 1. based on 2,000 Mw (Capa™ 2200A) 2. based on modified Caprolactone co-polymer (Capa™ 612065). 1. 基于 2,000 的分子量 (Capa™ 2200A) 2. 基于改性 Caprolactone (己内酯) 共聚物 (Capa™ 612065)。 In each case the polyol was made into a polyurethane acrylate, using IPDI and HEA. 均使用 IPDI(异佛尔酮二异氰酸酯)和 HEA(丙烯 酸羟乙酯)将多元醇制成聚氨酯丙烯酸酯。 Both samples appeared similar immediately after preparation. 经过制备后,两种样品的表现相似。

Experimental (cont.) 实验(续) 2h 2 小时 “未改性”样品开始变得“不 透明” 2,5 小时 开始变白 3 小时 完全变白,具有相当高的粘, 但仍不是固态 > 3 小时 已变为固态 “unmodified” sample starts To look “opaque” 2,5 h It begins to look white 3h It is completely white, really high viscous but still not solid > 3h It has become solid NB. After 2 hours stored at 60°C, both samples are liquid once more. 注意:在 60°C 下保存 2 小时后,两种 样品都再次变成了液体。 The “modified” sample remains clear throughout “改性”样品仍保持完全透明

Conclusions 结论  Tg can be controlled to allow formulation of hard or soft coat formulations.  Hard coats are greatly influenced by cross-link density  Dendrimer acrylate (BoltornTM) gives balance of hardness resistance, Tg and toughness.  Soft feel formulation is more dependent on the secondary Tg.  A balance of cross-link density, molecular weight and linear structure gives best combination of resistance and low Tg.  High molecular weight Caprolactone based Urethane acrylate gives resistance and relatively low Tg, but crystallinity must be controlled by use of copolymerisation with Lactide.  通过对Tg 的控制可获得硬质或软质涂料配方。  硬质涂料主要受交联密度影响。  超支化丙烯酸酯 (BoltornTM) 可实现硬度、 Tg 和韧性的完美平衡。  柔触觉配方更多取决于 其次级Tg 。  平衡交联密度、分子量和线性结构实现了 耐受性和低 Tg 的完美组合。  基于高分子量 己内酯的聚氨酯丙烯酸酯具有耐 受性和相对较低的 Tg,但其结晶度必须通过与 丙交酯的共聚作用进行控制。
